Output a warning log when 'mapperLocations' was specified but matching resources are not found

[lmiroslaw]

I found out someting interesting. mapperLocations property in my xml configuration file points to non-existing path:

 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="typeAliasesPackage" value="com.ucware.ucpo.statemachine.model"/> <!-- Register the short names of beans as aliases -->
    <property name="configLocation" value="classpath:mybatis-config.xml"/>
    <property name="mapperLocations" value="classpath*:/com/state/persistence/mapper/*.xml" />
</bean>

Still org.mybatis.spring.SqlSessionFactoryBean reports no exception.
this.mapperLocations is empty and execution continues.

In my case the correct link to the mapper is:
classpath_:/com/missing_entry/state/persistence/mapper/_.xml

Should not the exception be thrown ?

I use mybatis-spring.1.2.0.

Sorry but it is not clear to me that in case you use a mapperLocation property the search should get at least one result.

Getting zero results is indeed suspicious. It looks like a mistake but we cannot be 100% sure that it is a mistake.

That's true. It turned out my xml missed the definition of the . This is a reason why was empty. However, it would be nice to see this error in the log as it takes some time to figure it out.

You are right. I will add a warning for that.

I've fixed this issue.
Change to output a warning log when 'mapperLocations' was specified but matching resources are not found. If you want to prevent a warning log on production environment, please change log level of SqlSessionFactoryBean to error or higher.
